Welcome ot HF. I have the NX-200, because it fit my big 'ol backside better, and don't really use the pockets for warmth reasons. I use them to store items off the trail and as a place to keep items that I may need during the night that I don't want in the hammock with me. They are functional but again I don't use them for warmth. I have a Kick Ass Quilt Under Quilt (KAQ UQ) that I use instead. When I ordered my CJH fit/comfort was the goal, had a little extra Uncle Sammy Money that year!!!!! I have stayed out in 50*F weather with nothing but a SI sleep mat (uninflated), a fleece blanket and weather shield deployed with no real issues, I was shilly but not freezing. I hope this helps or it may just be rambling again about my CJH.
